Components

DOIs may be assigned to items that are part of a journal article, book chapter, or most other content types. Component records are often registered for figures, tables, and supplemental materials associated with a journal article.

Constructing component deposits

Components may be deposited along with their parent DOI or they can be deposited by themselves in a separate XML file as a 'stand alone' component. Components have their own metadata which is distinct from that of the parent DOI(s).

Components may belong to more than one parent item. For example, two journal articles may include the same component DOI.
